I am a U.S Citizen now (as of 8/2/07) and I also hold my citizenhip with Pakistan. Is there anything at all I have to do to be recognized as a dual Citizen? I have a Valid Pakistani Passport and I have already applied for a U.S Passport. I intend to make a trip aboard in the near future but I am NOT planning to get a PK visit visa on my U.S passport. I plan to use my U.S passport at departure from the U.S and my PK passport at arrival in Pakistan and vice versa when returning back. Is there anything at all that I need to know or should I be worry free?
